PVC muaj ob hom khoom siv: PVC tawv thiab PVC mos. Lub npe scientific ntawm PVC yog polyvinyl chloride, uas yog cov khoom tseem ceeb ntawm cov yas thiab feem ntau siv los ua cov khoom yas. Nws pheej yig thiab siv dav. PVC tawv suav txog li ob feem peb ntawm kev ua lag luam, thaum PVC mos suav txog ib feem peb. Yog li, qhov txawv ntawm PVC mos thiab PVC tawv yog dab tsi?
- Ntau yam degrees ntawm softness thiab hardness
Qhov sib txawv loj tshaj plaws yog nyob rau hauv lawv qhov sib txawv hardness. PVC tawv tsis muaj cov khoom ua kom mos, muaj kev ywj pheej zoo, yooj yim rau kev tsim, thiab tsis yooj yim tawg, tsis muaj tshuaj lom thiab tsis muaj kuab paug, khaws cia ntev, thiab muaj txiaj ntsig zoo rau kev txhim kho thiab siv. PVC mos, ntawm qhov tod tes, muaj cov khoom ua kom mos uas muaj qhov mos zoo, tab sis nws yooj yim tawg thiab nyuaj rau khaws cia, yog li nws siv tau tsawg.
- Lubcov ntawv thov ntau yamtxawv
Vim nws qhov kev ywj pheej zoo, PVC mos feem ntau yog siv rau saum npoo ntawm cov ntaub pua rooj, pem teb, qab nthab, thiab tawv; Cov polyvinyl chloride tawv feem ntau yog siv rau hauv cov kav dej PVC tawv, cov khoom siv, thiab cov ntaub ntawv.
3. Lubcov yam ntxwvtxawv
Los ntawm qhov pom ntawm cov yam ntxwv, PVC mos muaj cov kab ncab zoo, tuaj yeem nthuav dav, thiab muaj kev tiv taus zoo rau qhov kub siab thiab qis. Yog li ntawd, nws kuj tseem siv tau los ua cov ntaub pua rooj pob tshab. Qhov kub ntawm kev siv ntawm PVC tawv feem ntau tsis tshaj 40 degrees, thiab yog tias qhov kub siab dhau, cov khoom PVC tawv yuav raug puas tsuaj.
4. Lubcov khoomtxawv
Qhov ceev ntawm PVC mos yog 1.16-1.35g / cm ³, Tus nqi nqus dej yog 0.15 ~ 0.75%, qhov kub hloov iav yog 75 ~ 105 ℃, thiab tus nqi molding shrinkage yog 10 ~ 50 × 10- ³cm/cm. Feem ntau, PVC tawv muaj txoj kab uas hla ntawm 40-100 hli, phab ntsa sab hauv du thiab tsis yooj yim tawg, tsis muaj qhov tawg, tsis muaj tshuaj lom, tsis muaj kuab paug, thiab tiv taus xeb. Qhov kub ntawm kev siv tsis pub tshaj 40 degrees, yog li nws yog cov yeeb nkab dej txias. Zoo tiv taus kev laus thiab tiv taus hluav taws.
